TO ALL WHOM IT MAYOONOERN:

Be it known that I, JAMES P. DAVIS, of Stiles, in the county or" Oconto, and State of Wisconsin, have invented a. new and improved Bunk for Logging-Sleighs; and I do hereby declare that the following is a full,

clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same, ref-v I erencc being bad to the accompanying drawings,-forming part of this specification,

Figure 1 is a top or plan view of my improved bunk.

Figure 2 is a vertical longitudinal section of the same, taken through the line x x, fig. 1.

Similar letters of reference indicate corresponding parts. i

My invention has for its object to furnish an improved-bunk for attachment to logging-sleighs hy the use of which the logs of the lower tier will he preventedfrom spreadiiig while loading the upper tier or tiers, and which will enable the logs to be bound and unloaded in much less time than is necessary when the logs are bound in the ordinary manner; and it consists in the bunk, the ends of which are slotted vertically, and which has log-chains attached to it at or near thein'ner ends of the said slots, as hereinafter more fully described.

A is the bunk, two of which are used upon the sleigh, to which they are attached in the ordinary manner.

The bunksA are slotted vertically from their ends nearly to their centres, as shown in figs. 1 and 2. a are pins attached to the bunk A, and crossing the said slots to support the chainsaud prevent the said 'bnnk frorn splitting.. B are short chains, the inner ends of which are secured to the bunk A within the slots, and at 01' near'their inner ends, as shown in figs. 1 and 2. To the outer ends of the chains B are attached, or upon them are formed, dogs 6, which are driven into the sides of the outside logs to hold them in place. To the chains B, at,theends of the bunk A, are attached rings b ifor convenience in attaching the log-chains by which the upper tier or tiers of logs are bound.

In using my improved bunk, the first log is rolled to the farther end of the bunks, and the dogs 6 of the chains B driven into its side. The other logs of the first tier are then rolled into place, and the dogs I) of the other chains '13 are driven into the side of the last log, thus securing the first tier of logs inplace. The logs of the upper tier or tiers are thenrolled on, and the load is bound on by passing the log-chains around it, and securing them to the rings 6 of the log-chains B. v

I claim as new, and desire to secure by Letters Patent- An improved logging-bunk, A, the ends of which are slotted vertically, and which has log-chains B attached to it within the said slots, and at or near their inner ends, substantially as herein shown and described,

writer the purpose set forth.
